Not Worth It: Useless Screwdriver

This screwdriver doesn't work for automotive repairs because it constantly loses calibration and the notification direction is confusing.

Pros
  • None.
Cons
  • Inaccurate and unreliable.

Revainrating 4 out of 5

No existing support number, email or website. Incorrectly tested or incorrect information in the manual.

First of all I don't understand how you think someone can get away with selling a product with different specifications but not saying "Made in [country]" at least as far as I can remember , is illegal. ray jay ltd which is good as it is based in taiwan but i don't speak taiwanese. Maybe I can ask my question here: 1. Why does the picture in the manual not match the product specification? If I wreck my engine because the manual says no less than 50 lb lb as opposed to the product description…

Pros
  • Free for educational purposes
Cons
  • Null

Easy to use and seems accurate

I've used this to install a roof rails and trailer hitch on my car This required a torque range of 3 ft-lb, 9 ft-lb, 23 ft-lb, 47 ft-lb and 72 ft-lb This unit did excellent for this application Although this device only "warns" at a minimum of 5 ft-lbs, it still displays a lower torque range (0-5 ft-lbs. (47/72 ft-lbs) down to 0.2 ft-lbs). lbs accurate. I also used a tape measure/luggage scale for lower torques and it seemed accurate enough. Although this device is small it definitely adds bulk

Pros
  • 1/4" universal hex bit holder with quick release. Comes with 6 wrench bits, 14 screwdriver bits and 1 magnetic bit extender
Cons
  • Almost everything is fine
